Polyphenylsulfone-hBN Composite Insulation

2020 IEEE 3rd International Conference on Dielectrics (ICD), 2020
The goal of this work was to develop and characterize high-temperature, thermally conductive electrical insulation to improve thermal management in high power density electric motors. Polyphenylsulfone (PPSU) films were extruded with up to approximately 24 wt% of either micro-sized hexagonal boron nitride (hBN) or a mixture of micro-and nano-sized hBN ...

Electronic charge exchange at insulator-insulator interface in insulating composites

Proceedings of 1994 4th International Conference on Properties and Applications of Dielectric Materials (ICPADM), 2002
The charge exchange at the insulator-insulator interface in insulating composites is affected by the direction of the carrier transport and carrier species. In this paper the charge exchange process at the PS-PMMA interface was discussed on the basis of asymmetric photoconduction and contact charging.

Composite Post Insulators

2013
In contrast to composite long rods, composite post insulators are subjected mainly to loads which act perpendicular to the longitudinal axis of the insulator and thus produce bending stresses over the cross-section of the insulator. As a result of this bending load, composite post insulators use FRP rods of substantially greater diameter compared to ...
